Promoter Frank Warren has revealed that Carl Frampton can expect a blockbuster unification title fight if he can dethrone IBF world featherweight champion Josh Warrington on Saturday night.

Warren has already held talks with fellow legendary promoter Bob Arum about the winner of this weekend's Manchester Arena clash going on to face the exciting WBO featherweight title holder Oscar Valdez in what would be one of the biggest fights of the year.

Frampton, looking sharp at yesterday's open work-out in Manchester, is aiming to become a two-time featherweight champion of the world when he takes on Warrington who is making the first defence of the title he won when eclipsing Welshman Lee Selby in May.

Warren said: "Saturday night's fight is guaranteed to be a great fight. All the ingredients are there because you have two top quality fighters. If Carl was to win then I would be looking to bring Oscar Valdez to Windsor Park.

"What a fight that would be for Belfast. I love putting on shows there because the fans are so knowledgeable and having spoken to Bob Arum only last week, it's a real possibility. Our shows are now being shown on ESPN which he has a deal with so I don't see that being a hard fight to make."

Warren added: "But, of course, Carl has to get past Saturday night first of all and that is not going to be easy. Whenever I look at the fight I keep coming at it from different angles. You can make a case for both guys winning the fight. One thing is for sure, they're both going to have to step up to another level - and they will."

"It's just pathetic that Hearn decided to put on that show the same night as our bill and the people who will suffer are the four fighters because their purses will be hit," added Warren.

"It's alright Hearn saying it will only take away around 50,000 buys away from his show but even if that is correct, that's still three-quarters of a million quid that could be going to the fighters.

"But let's get it right, there is no comparison between the two shows. Frampton and Warrington is a top-quality world title fight and the other one is headed by two heavyweights at British level. Whyte has already been chinned by Anthony Joshua and Chisora has lost seven out of eight meaningful fights.

"It's a bit like going in to buy your wife a Ralph Lauren watch or deciding to buy the knock-off one from the guy on the street corner - which show would you rather see? But even at that, it's just not right that at Christmas time fans are being asked to pay for two pay-per-view shows."
